Tertiary-amine-free, non-planar, fluorine-containing tetrafunctional epoxy and its application as high performance matrix

Self-healing of electrical damage in insulating robust epoxy containing dynamic fluorine-substituted carbamate bonds for green dielectrics

“…This suggests that introducing fluorine atoms into epoxy networks can improve the rigidity of the materials. 45,46 This can also be proved by tensile tests (Fig. S5 and Table S1, ESI†).…”

Aromatic tetra-glycidyl ether versus tetra-glycidyl amine epoxy networks: Influence of monomer structure and epoxide conversion

“…Liu et al described the synthesis and characterisation of a tetrafunctional, nitrogen-free epoxy resin and showed that a blend of the monomer with diglycidyl ether of bisphenol A (DGEBA) had a Tg similar to TGDDM [17]. Further work by Xing et al showed similar results using a nitrogenfree tetrafunctional epoxy when blended with up to 60 wt% DGEBA [18].…”

Cure Kinetics and Network Development of a Very High Tg Naphthalene-Based Epoxy Amine Network

“…20 Xing et al also synthesized a tetrafunctional epoxy resin, free of tertiary amine, which showed improvements in T g compared to a DGEBA-based resin at 20 mol % loading and again attributed this to a lack of cyclization. 21 The primary disadvantage related to processing constraints arise from their high viscosity and comparative intractability.…”

“…Liu et al synthesized a nitrogen-free multiaromatic tetrafunctional epoxy which displayed markedly improved conversion and properties similar to TGDDM which they attributed to lower steric hindrance .
